The Jackson Laboratory (JAX) and the University of California, Davis have initiated a new phase in their ongoing research collaboration by sharing resources and core services. UC Davis will benefit from on-site educational programs at the JAX mouse facility in Sacramento, Calif. JAX will provide mouse colony management services for UC Davis investigators, expediting research discoveries by preventing transportation delays. Shared access to the advanced imaging technologies at UC Davis and JAX’s mouse cryopreservation facilities will enable both institutions to save on infrastructure costs.
